DCFS' indicated finding of sexual penetration against woman, then age 19, was against the manifest weight of the evidence. That woman had sexual relationship with 16-year-old homeless minor who had been occasionally staying at home of woman's parents. Court did not specifically find that minor and Respondent were "residing together"; Status of persons entrusted to care for minors is not the focus or purpose of adjudicatory hearing. (APPLETON and KNECHT, concurring.)
